That is actually a really good question......
Sometimes (not always) a person goes into shock it takes a long time to actually allow your self to feel again and as hard as you may try a shock could have locked up a huge part of the emotional body. with time it does get unlocked and emotions come back, you can also spend days with tears rolling but you are not sure why, it is what I call a cleansing but with time you do feel again and Marc Klass has had a lot of time go by from when his trauma first happened..
iirc, Marc has been consistent in his response from that horrible Day One until now.
Yeah, I know, "ppl grieve differently"; and most of them, not on TV, let alone so soon.
